Amonochromatic (single frequency, single wavelength) light ray in air (n= 1) enters a glass prism (n= 1.5). in the glass prism a. both the frequency and the wavelength are the same as in air
b. the frequency is the same, but the wavelength is greater than in air.
c. the frequency is the same, but the wavelength is smaller than in air.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

If the new moon happens on january 15th, what shape will it be on february 6th?

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
